Definitions

  • the present invention relates to a flow control device and more particularly to a flow control device for an automated sample preparation system, a system, as well as a method therefore.
  • test-tubes In some areas of laboratory testing which needs a high throughput, high density carriers for test-tubes are commonly used. Such high density carriers are commonly denoted well-plates or cartridges and exists in various sizes, such as for example 24, or 96-well-plates. The number indicates the number of test-tubes.
  • solid phase extraction SPE
  • test-tubes which are open both in a proximal end and in a distal end with a separation media arranged there between. Upon passing the sample through the separation media retention of the target molecule occurs in the separation media.
  • the guiding of the first solvent is performed by applying a pressure to one end of the cartridge by means of a gas.
  • This pressure is often supplied via a flow path with a high flow resistance in order to minimize the effect of possible leakages in the connection to the test-tube of the carrier between neighboring test-tubes.
  • a step of drying may be performed by means of flowing a gas at an overpressure through the cartridge at higher flow rate compared to the flow rate of the first solvent. Such increased gas flow will improve the drying of the residual first solvent.
  • a problem of the known solution is that each individual sample must be dried which takes a long time.
  • a problem of the above solution is that vacuum is used to draw the liquid through a test-tube, and the drying is performed by means of blowing a gas through the test-tube.
  • the use of vacuum for drawing the liquid through the test-tube means that the available maximum vacuum is approximately 1 Bar, which in some cases may be not be sufficient.

  • Fig. 8 the control means 804 is closed whereby the cavity 401 is not supplied with a fluid flow from the fluid source 805. This causes the membrane 302 to be in a flat state or to be deflected into the cavity 401.
  • the maneuverable fluid source 805 supplies compressed air to the first inlet 103 of the flow control device. Since the membrane is not engaging the inlet 105 of the primary flow path both the primary flow path and the secondary flow path are open for fluid flow to a test-tube 806 of the array 801.
  • the membrane of the flow control device 100 is in its second position. This is caused by opening the control means 804 such that compressed air flows into the cavity 401 from the maneuverable fluid source 805, which causes the membrane 32 to deflect and block each inlet 105 of the primary outlet. This causes the primary flow path to be interrupted and the secondary flow path is the only flow path from the maneuverable fluid source to each test-tube 806 of the array 801. This causes a reduced flow of fluid from the maneuverable fluid source to the test-tubes of the array 801. This reduced flow is suitable for moving a liquid through the test tubes.

  • the method according to t comprises:
  • the method involves one or more additional steps of:
  • the first liquid is immiscible with the second liquid.
  • the first liquid is an aqueous liquid, such as a biological sample or a sample dissolved in water
  • the second liquid is an organic liquid, such as any organic solvent commonly used in this area.
  • the first liquid is water and the second liquid is dichloromethane or hexane.
